Specification of Letters Patent.

Patented July 14,1908.

Application filed January 8, 1908. Serial No. 409,771.

To all whom it may concern:

Be it known that I, SAMUEL J. SILL, a citizen of the United States, anda resident of the city of Buffalo, county of Erie, and State of NewYork, have invented an Improved Machine for Removing Wrappers from Hoseafter the Vulcanizing Operation and for Rewinding said Wrappers on Mandrels, of which I do declare the following to be a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this speclfication.

In the manufacture of sections of rubber hose, such as are commonlyemployed in railway air brake systems, (these sections be ing usuallyabout 22 inches long), it is customary to wrap the hose, prior to' thevulcanizing operation, with wet cloths or rags which serve to insure theuniform distribution of the soft rubber cover of the hose until it hasbeen set by the vulcanizing process. After the hose and the vulcanizingmandrel whereon it is mounted have been withdrawn from the vulcanizer,the wrappers or rags are removed from the hose and are soaked or wetwith water ready for subsequent use.

The present invention has for its object to provide an improved machinefor removing the wrappers or rags from the hose after the vulcanizingoperation and for wetting and rewinding these rags or wrappers on amandrel so that they may be conveniently used thereafter for thestraight wrapping of' other sections of unvalcanized hose.

The invention consists in the features of novelty hereinafter described,illustrated in the accompanying drawings and particularly pointed out inthe claims at the end of this specification.

In the drawings, Figure 1 is a plan view of the improved machine. Fig. 2is a front elevation thereof. Fig. 3 is a cross section. Fig. 4 is adetail section.

1 designates the bed-plate of the machine that is mounted upon suitablelegs or supports 2. The central portion of the bedplate 1 is cut away,as shown, and beneath this cut-away space is held a-tank or pan 4 fromend to end of which extends a perforated ipe 5 through which water willbe admitte through a suitable supply pipe 6. I

An outlet pipe 7 connects with the tank 5 to conduct water therefrom.

From the top of the bed-plate 1 rise the brackets 10 and 11 that carrythe centering rods 12 and 13, these rods having coneshaped ends 14 toenter and center the ends of the hose-carrying, vulcanizing mandrelsfrom which the wrappers or rags are to be unwound. The centering rod 13is shown as screw-threaded to pass through a corresponding threadedopening in the standard 11 and the outer end of this rod 13 is providedwith ahand-wheel whereby it may be adjusted. The heads 14 are rotatablysecured to the rods 12 and 13 by pins 14 (see Fig. 4). The rod 12 ismounted in manner free to slide through the opening in its bracket orsupport 10 and to the outer end of the rod 12 is pivotally connected asat 15 a lever 16 whereby the rod 12 may be shifted. One end of the lever16 is pivoted as at 17 to a bracket 18 that is bolted to the bed-plate1, and, adjacent the opposite end of this lever 16 is connected a cord20 that extends over a pulley 21 and has connected to its lower end aweight 2-2, the weight 22 serving to draw inwardly the lever 16 so as topress inward the rod 12 and thus hold the vulcanizing mandrel upon thecenters 14 whereon it will revolve as the wrappers or rags are woundtherefrom. The pulley 21 is mounted on a bracket 23 that is bolted tothe front of the bed-plate, the upper end of this bracket having alaterally extended rest 23 for the outer end of lever 16 and a stop 23to limit its movement. When a vulcanizing mandrel has been placedbetween the centers 14 at the inner ends of rods 12 and 13, the weight20 will cause the lever 16 to force inward the rod 12, thereby insuringthe active engagement of the rotatable centers 14 with the open ends ofthe vulcanizing mandrel.

Upon the top of the bed-plate and the opposite ends of the chamber ortank 4 are mounted the bearing-blocks 30 in which will be revolublysupported the mandrel 31 (in dicated by dotted lines, Fig. 1), whereoneach wrapper or rag will be wound after it has been withdrawn from thevulcanizing mandrel and has been wet with water, as will presentlyappear. 'Suitable caps 32 will set over the ends of the mandrel 31,these caps being detachably connected so that the mandrel can be removedfrom the machine after a sufficient number of wrappers or rags have beenwound thereon. ing-blocks 30 are formed with perforated,

' tain the cap securely in position.

offset lugs orflanges 35 at their opposite sides, and each of the caps32 is shownas provided at one side with a depending, perforated arm 36through which will pass a bolt 37 that pivotally connects the cap to thebearing-' block 30. At its opposite side each cap is formed with a slot38 through which will pass a bolt 39 that is pivoted as at bolt 40 tothe bolt that passes through the lugs at the front of the correspondingbearing-blocks 30, and this bolt 39 has a screw-threaded upper end toreceive a wing nut 41 which, when the bolt is slipped within the slot 38will serve to re- When, however, it is desired to remove the mandrelafter a sufficient quantity of wrappers or rags have been wound thereon,the o erator will loosen the wing nut 41 and swing 'orward the bolt soas to permit the caps 32 to be turned backward in order that the filledmandrel may be withdrawn. At one end of the bedplate and at a pointadjacent one of the bearing-blooks for the rewinding mandrel, is placeda journal standard 01' bearing wherein is mounted one end of a drivepulley shaft 51, the outer end of this shaft 51 being journaled in asuitable bearing boX 52 mounted at the upper end of the curved bracket53 that is bolted as at 54 to the end of the machine. The inner end ofthe drive pulley shaft 51 inside the bearing boX 50 is provided with anenlargement 55 and a suitable cap or collar 55 will be mounted upon theouter end of the shaft outside the bearing 52 to hold the same againstendwise movement. Upon the shaft 51 is revolubly mounted the drivepulley 56 having friction faces at its opposite sides and upon the shaft51 at the oposite sides of the pulley 56 are splined friction clutchdisks or members 57 and 58. The friction disk or member 57 has anannular groove 59 formed in its hub, and into this groove 59 willproject pins 59 on the bowed portions of a clutch lever 60 whereby thefriction disk 57 will be moved into and out of engagement with the drivepulley 56. The clutch lever 60 is pivotally mounted as at 61 upon abracket 62 projecting from the end of the machine. The en largement onthe inner end of the shaft 51 inside the journal bearing block 50 isprovided with a chamber or cavity 64 to receive one end of the mandrelwhereon the wrappers or rags will be wound. As shown, a pin 65 projectsinto the chamber 64 to engage with the end of the mandrel whereonthewrappers or rags will be wound as they are drawn from the vulcanizingmandrel.

As shown, there are two boards and 71 on the top of the bedlate 1 and tothese boards are hinged the p ates or covers 73 and 74 the under facesof both of which will be covered with zinc. In operation, the wrap ersfrom the tube section are passed down 1nto the tank below the perforatedpipe 5 and then over the mandrel 31, as indicated in dotted lines inFig. 3. Mandrel 31 is then driven from shaft 51 to unwind the wrappersfrom the tube and wind them up on the mandrel 31 when the frictionclutch is thrown into operation. At the same time the wrappers aresoaked for reuse. The plate 73 not only serves to prevent the water fromsplashing over onto the floor, but, as it is provided with spring hinges72 it also serves to place a certain amount of friction on thewrappercarried by the hose so as to prevent a too loose unwinding of thewrappers from the hose. The front board or plate 74 also prevents thesplashing of water in forward direction and is adapted to bear on thesurface of the wrappers or rags as they are being wound upon therewinding mandrel, thereby preventing wrinkles being formed in thewrappers. This is an important feature since, when the wrappers or ragsare taken from the rewinding mandrel and wound upon the hose preparatoryto the vulcanizing operation, it is essential that the wrap er shall belaid around the hose uniform y without wrinkling, in order to preventthe marring of the outer cover of the wrap er which becomes softenedduring the vu canizing process and would, therefore, take the impressionof any creases or wrinkles in the wrappers.

It is obvious that changes may be made in the details set forth withoutdeparture from the essentials of the invention.
